In light of our recent announcements regarding large enterprise-class systems, now seems like a good time to talk about the incredible value Power provides now in its scale-out portfolio. The unfortunate truth is that questions about price tend to get redirected. We’re urged instead to look at value, to focus on the long-term investment, and consider a range of new possibilities. But in a world where budgets are firm – and not flexible whenever something really good comes along – clarity about capital expenditures for Linux... [More]

This has been a great week for Power Systems, especially if you’re fan of the 1-2 socket (scale-out) side of the portfolio and innovative technology that leverages Linux. I just returned from our annual Enterprise conference, an event we do every fall to bring together clients and partners with our SMEs to explore the latest developments in infrastructure. Major announcements were made by System z, Storage, and Power Systems. I also had a couple of sessions at the conference, and was excited to talk about some of these new... [More]

P { margin-bottom: 0.08in; }A:link { } This article describes a method to optimize a PowerKVM guest to minimize NUMA effects when dedicating PCI adapters using PCI passthrough to optimize performance and reduce CPU overhead to achieve near baremetal performance on a POWER8 system. KVM guest domains configured with dedicated high speed I/O adapters through PCI passthrough can benefit from optimizing location of CPU and memory in the host. This tutorial shows how to add commands to the domain xml file to pin CPU and memory to a specific... [More]

Installing native RubyGems packages in the new Power8 Ubuntu Little Endian platform IBM Power8 Systems now run the popular Ubuntu distro. With Ubuntu it is now very easy to run ruby based applications on Power8 systems and get all the advantages of an enterprise class system (e.g. up to 2TB of RAM, 2 CPUs with up to 12 hardware threads each and so on). Ruby applications often make use of packaged ruby gems downloaded from rubygems.org. But some of these ruby gems include native extensions in the form of source code tar balls which need to be...

Game theorists use the example of Prisoner’s Dilemma to show how two rational people might refuse to cooperate with each other, increasing the suffering on both sides. The same can be said for businesses. It’s easy for a company to refuse to be the first to share for fear of being betrayed by competitors. Historically, the possible innovation and growth rewards from collaboration didn’t outweigh the costs of potential betrayal. But times have changed. Now the costs of not cooperating far outweigh the... [More]

A new Solution Guide to implement MongoDB in IBM Power Systems running Linux featuring the new IBM POWER8 technology is available. This white paper describes MongoDB (from humongous), which is an open source NoSQL style, document database with dynamic schema. The paper discusses the main features of the MongoDB solution, its architecture and implementation on IBM Power Systems running Linux. The target audience is users and system integrators who implement MongoDB on IBM Power Systems running Linux servers. No familiarity with MongoDB or... [More]
